Available in PDF, EPUB and Kindle. Book excerpt: NOUS PRESENTONS PLUSIEURS CONTRIBUTIONS REALISEES DANS LE CADRE DU DEVELOPPEMENT D'UNE APPROCHE POUR LA VERIFICATION FORMELLE DE SYSTEMES PARALLELES. LA PREMIERE CONTRIBUTION EST UN OUTIL THEORIQUE DE MODELISATION, LES GRAPHES ABSTRAITS ANNOTES (GAA). CES OBJETS MATHEMATIQUES PERMETTENT DE MAINTENIR LA SEPARATION ENTRE LA STRUCTURE FINIE DES DESCRIPTIONS ET LEUR CONTENU SEMANTIQUE QUI EST GENERALEMENT INFINI. MALGRE LEUR RELATIVE SIMPLICITE THEORIQUE ILS CONSTITUENT UN MOYEN DE DESCRIPTION PARTICULIEREMENT PUISSANT ET ACCESSIBLE DE NOMBREUSES PROPRIETES SOPHISTIQUEES (E.G. COHERENCE GLOBALE, FRAICHEUR, AUTHENTIFICATION). LA DEUXIEME CONTRIBUTION EST RELATIVE A LA CONCEPTION D'UNE TECHNIQUE DE VERIFICATION PARTICULIEREMENT PUISSANTE QUI PERMET D'EXPLOITER L'ORDRE PARTIEL DES EVENEMENTS POUR REDUIRE A LA FOIS LA COMPLEXITE DE L'EXPRESSION D'INVARIANT ET CELLE DE LA VERIFICATION. LA TROISIEME CONTRIBUTION EST UNE APPLICATION AU DOMAINE DE LA VERIFICATION DES PROTOCOLES D'AUTHENTIFICATION. L'APPROCHE SEPARE LA MODELISATION DES CONNAISSANCES, DE LA MODELISATION DE NOTIONS DE NATURE TEMPORELLE COMME LA FRAICHEUR. CETTE APPROCHE EST ILLUSTREE POUR LA VERIFICATION D'UN PROTOCOLE D'AUTHENTIFICATION PARTICULIEREMENT REPRESENTATIF, CELUI DE NEEDHAM-SCHROEDER. LA QUATRIEME CONTRIBUTION EST UNE THEORIE SEMANTIQUE POUR L'UNIFICATION DES PARADIGMES DE PROGRAMMATION PARALLELE, FONCTIONNELLE ET IMPERATIVE. NOTRE THEORIE SEMANTIC EST COMPOSEE ESSENTIELLEMENT D'UNE SEMANTIQUE STATIQUE ET DE DEUX SEMANTIQUES DYNAMIQUES: L'UNE OPERATIONNELLE ET L'AUTRE DENOTATIONNELLE

Available in PDF, EPUB and Kindle. Book excerpt: L'introduction des nouvelles technologies de l'information et de la communication dans les systèmes automatisés entraîne un accroissement de la complexité des fonctions qu'ils supportent. Cet accroissement de la complexité a un impact sur la sécurité des systèmes. En effet, leurs propriétés ne sont plus réductibles aux propriétés de leurs constituants pris isolément mais émergent d'un réseau d'interactions entre ces constituants qui peut être à l'origine de comportements néfastes et difficiles à prévoir. Notre conviction est que le développement sûr de ces systèmes doit combiner des approches pragmatiques orientées « système », qui tiennent compte du facteur d'échelle réel d'une automatisation pour appréhender le fonctionnement global du système et son architecture, avec des approches plus formelles qui permettent de s'assurer que les propriétés intrinsèques des constituants contribuent efficacement au respect des exigences « système » formulées par les utilisateurs. Le travail présenté dans ce mémoire définit donc une approche méthodologique basée sur le formalisme SysML (System Modeling Language) permettant l'identification, la formalisation et la structuration d'exigences globales relatives à un système, puis leur projection, sous forme de propriétés invariantes, sur une architecture de composants. La vérification des exigences de sécurité, repose alors, d'une part, sur un raffinement prouvé (par theroem proving) des exigences « système » permettant d'établir leur équivalence avec un ensemble de propriétés intrinsèques relatives à chacun des composants, et d'autre part, sur la vérification formelle (par model checking) de ces propriétés intrinsèques.

Book excerpt: Weaponry is a central factor in any kind of military activity. The incorporation of weapon systems into aircraft and their integration and satisfactory operation is a topic of major importance to armed forces and manufacturers of weapons and aircraft alike. The scope of this symposium was to critically review the overall state-of-the-art in aircraft weapon system compatibility and integration and to illuminate possible paths for future development and provide beneficial ideas and experience. Sessions dealt with the following topics: Theoretical methods and modelling techniques, Experimental and flight test techniques, Integration processes and programmes, Addressing future challenges. This symposium produced many excellent papers providing broad coverage of the weapons integration issues. There were many common threads with regard to the analysis, wind tunnel testing, and flight testing. Computational fluid dynamics (CFD) is proving to be a useful technique; wind tunnel testing is very important in the weapons integration process; but, flight testing has to be the final phase of the weapons integration process. This symposium produced a level of cohesiveness between the analysts and testers; however, full agreement as to the mix of analysis and testing did not evolve. In order to reduce the cost of weapon integration, certification, clearance, and flight testing, weapon integration analytical techniques, including CFD and wind tunnel testing, and flight testing need to become more of an integrated process. The knowledge gained and information shared at this symposium should assist the participants in developing a more integrated process in order to provide NATO nations with fully integrated weapon systems at an affordable price.

Book Synopsis Law, Society, and Industrial Justice by : Philip Selznick
Download or read book Law, Society, and Industrial Justice written by Philip Selznick and published by Quid Pro Books. This book was released on 2020-05-23 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: LAW, SOCIETY, AND INDUSTRIAL JUSTICE is a foundational study of workplace justice, still engaging and referenced a half-century after its original publication. The 50th Anniversary Edition adds an extensive, substantive Foreword by Berkeley’s Lauren Edelman. She writes that the book “remains important for how it conceptualizes law, for how it conceptualizes organizations, and for the theory Selznick offers regarding the moral evolution of organizations as they become ‘institutions,’ or living entities infused with values.” It is “a profound book for many reasons,” as she critically examines. Norms and values still matter in organizational governance — even in what amounts to “private government” — as this classic work reminds us. “Selznick’s classic text invites the reader to understand the interplay of formal and informal structures that produce new organizational norms, which, at their best, would replace workplace arbitrariness with due process protections like those embodied in the Rule of Law. It is not just an extraordinary contribution to the fields of sociology and jurisprudence, it is the theoretically foundational precursor to entire subfields in sociology and law.” — Laura Beth Nielsen, Chair, Department of Sociology, Northwestern University; Research Professor, ABF “Philip Selznick laid the foundation for one of law and society’s most vibrant areas of inquiry: law and organizations. Although this book has often been underappreciated, its 50th anniversary is a good opportunity to reassess its significance. Indeed, the current #MeToo movement lends more urgency to Selznick’s highly relevant ideas about conceptualizing organizations as legal orders, the importance of changing norms and values, the role of law within organizations, and organizations’ influence on the law.” — Ashley T. Rubin, Sociology, University of Hawai‘i at Manoa “Selznick’s study is undoubtedly the most erudite and imaginative example of the natural-law approach to appear. ... It is a very fine, even extraordinary piece of legal scholarship. It displays much craftsmanship, depth of learning, and creativity. It is elegant in style and graceful in presentation. Every legal sociologist should read it.” — Donald J. Black, American Journal of Sociology “A contribution, brilliant and substantial, to the literature on private government.” — Winston M. Fisk, American Political Science Review “Very enlightening and reminiscent of a good lecturer able to pull all the strings together chapter by chapter. ... The volume can be recommended to all students of law, industrial organization, and industrial relations.” — Industrial and Labor Relations Review

Book Synopsis The Dynamics and Challenges of Tetranormalization by : Henri Savall
Download or read book The Dynamics and Challenges of Tetranormalization written by Henri Savall and published by IAP. This book was released on 2013-03-01 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume continues the collaboration between the RMC book series and the French management research think tank ISEOR (Socio-Economic Institute for Firms and Organizations). Those familiar with Henri Savall’s and his colleague Véronique Zardet’s earlier work on the socio-economic theory of organizations will recognize their assessments of organizational dysfunctions and hidden costs – but in a different context. In their current work, the emphasis is on the tensions created by the wider environment – the idea of tetranormalization – and how those tensions shape and influence organizational life. Drawing on a wide range of examples from the news media and popular press, Savall and Zardet paint a disturbing picture of the underlying dynamics and challenges posed by a literal avalanche of standards and norms – which are often ambiguous and conflicting – that literally encompasses all that we do. Their analytic framework is composed of four “poles” – two social dimensions and two economic dimensions – that capture social norms and quality, safety and environment standards (the social dimension), and trade-related norms and accounting and financial standards (the economic dimension). Throughout the volume, Savall and Zardet’s analysis captures the myriad ways in which these dimensions interact, shaping the “rules of the game” that dictate how organizations compete and collaborate. Differentiating the “rules of the game” from “playing with” those rules, they delve into the subtleties and nuances that underlie these “poles,” providing further insight into how these forces are manipulated through lobbying and the seemingly 24/7 cycle of exposing, publicizing and rule-making surrounding social and economic as well as scientific and technological controversies. As Savall and Zardet argue, we are in the midst of a profound upheaval that will play havoc with our economic and social lives for some time to come. If we are going to exert influence on that reality, the challenges that we face moving forward must be conceptualized, constructed and implemented today, for, as they argue, “the road to durable prosperity will be a long haul.” Yet, moving beyond these challenges per se, they underscore that we are also presented with an exceptional opportunity – the very real opportunity to create a sustainable commitment to responsible and responsive organizational performance, one that can be fuelled and financed by our ability to translate the hidden costs that exist in all our organizations into productive, value-added activities and true wealth creation. Their analysis presents an intriguing challenge to traditional notions of corporate social responsibility, delving into the idea of “durably acceptable” responsibility, ways to facilitate greater stakeholder engagement, and how we can capture ongoing and sustainable improvement in organizational performance.
